Craftsman Cordless 4-1/2-in Small Angle Grinder

The Craftsman Cordless 4-1/2-in Small Angle Grinder, model CMCG400B, is a versatile and robust addition to any DIY enthusiast's toolbox. As someone who frequently tackles a variety of home improvement and metalworking projects, I found this grinder to be an excellent blend of power and convenience. Its cordless design allows for significant flexibility, making it perfect for both indoor and outdoor tasks.

Design and Build Quality

The first thing I noticed about this grinder is its solid build quality. The cast metal gear housing not only adds to its durability but also aids in dissipating heat during extended use. This is a crucial feature, especially when you're dealing with prolonged grinding sessions. The tool feels well-balanced in hand, thanks to its contoured over-molded handle, which enhances comfort and reduces fatigue.

The grinder's three-position handle is a thoughtful addition, allowing you to adjust it for better control depending on the task at hand. Whether you're left-handed or right-handed, or need to work at an awkward angle, this feature ensures you can maintain a firm grip and precise control.

Performance

Powered by an 8,500 RPM motor, this grinder doesn't shy away from demanding tasks. I used it to cut through metal skirting for a mobile home project, and it performed admirably. The tool-free guard adjustment is a boon, making it easy to reposition the guard for optimal safety and visibility without needing additional tools.

One of the standout features is its cordless nature, powered by a 20V MAX* Lithium-Ion battery. While the battery is not included, I paired it with a 4Ah battery from my existing Craftsman collection. The performance was impressive, but it's worth noting that the grinder does consume battery power relatively quickly. For heavier tasks, I recommend investing in a higher capacity battery, such as a 6Ah or 9Ah, to avoid frequent recharges.

Usability

The grinder is user-friendly, with a spindle lock that simplifies disc changes. However, I did find the trigger to be a bit sensitive. If not fully depressed quickly and firmly, the tool tends to shut off, even if you continue to press the trigger. This can be a minor annoyance, especially when you're in the middle of a precise cut or grind.

Another point of concern is the safety lock switch. In my experience, it sometimes failed to engage properly, which could potentially lead to accidental startups. This is something to be mindful of, particularly if you're working in a busy or cluttered environment.

Versatility

This grinder is not just limited to metalwork. I used it for a variety of tasks, including cutting ceramic tiles for a backsplash and removing rust spots from an old vise for a restoration project. The included disc worked well, and the tool's compatibility with a wide range of accessories, such as wire brushes and different cutting discs, makes it a versatile addition to any workshop.

Value for Money

Given its price point, the Craftsman Cordless Angle Grinder offers excellent value. It's a medium-duty tool that's well-suited for DIY projects and light professional use. While it may not match the performance of high-end, corded models for continuous heavy-duty work, it excels in portability and convenience.

Pros and Cons

Pros:

• Cordless Flexibility: No need to be tethered to a power source, making it ideal for outdoor and remote tasks.

• No Onboard Storage for Spanner Wrench: Changing discs requires keeping track of the wrench separately.

Conclusion

The Craftsman Cordless Angle Grinder is a solid, reliable tool that offers excellent versatility and convenience for a variety of tasks. Its cordless design, robust build quality, and user-friendly features make it a valuable addition to any DIY enthusiast's toolkit. While it does have a few quirks, such as battery consumption and a sensitive trigger, these are relatively minor issues that can be managed with a bit of preparation and care.

Would I recommend this tool? Absolutely, especially for those who already own Craftsman 20V MAX* batteries and are looking for a medium-duty grinder that can handle a range of tasks without the hassle of cords. For heavy-duty, continuous use, you might want to consider a corded model, but for most DIY projects and light professional work, this grinder is more than up to the task.
